When you upgrade PowerExchange, you must perform an upgrade installation on each of the following systems:

Each PowerExchange data source or target system
Windows system on which you will run the PowerExchange Navigator
PowerCenter Client or Informatica Developer client system
PowerCenter Integration Service or Data Integration Service system

To help you plan your upgrade, this chapter provides strategies for preserving existing PowerExchange data files. The chapter also describes several migration scenarios and lists the basic steps to follow for each scenario.

In addition to reviewing this chapter, see the upgrade considerations that are described in Upgrade Considerations. For detailed descriptions of the PowerExchange environment for each operating system, see PowerExchange Environment.
